Examples

This example shows how to create a TIFF image from scratch and save it to a file.

[C#]

string dir = "c:\\temp\\";

Aspose.Imaging.ImageOptions.TiffOptions createOptions = new Aspose.Imaging.ImageOptions.TiffOptions(Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.Default);
    
// Set 8 bits for each color component.
createOptions.BitsPerSample = new ushort[] { 8, 8, 8 };

// Set the Big Endian byte order (Motorola)
createOptions.ByteOrder = Aspose.Imaging.FileFormats.Tiff.Enums.TiffByteOrder.BigEndian;

// Set the LZW compression.
createOptions.Compression = Aspose.Imaging.FileFormats.Tiff.Enums.TiffCompressions.Lzw;

// Set the RGB color model.
createOptions.Photometric = Aspose.Imaging.FileFormats.Tiff.Enums.TiffPhotometrics.Rgb;

// All color components will be stored within a single plane.
createOptions.PlanarConfiguration = Aspose.Imaging.FileFormats.Tiff.Enums.TiffPlanarConfigs.Contiguous;

// Create a TIFF Frame of 100x100 px.
// Note that you don't have to dispose a frame explicitly if it is included into TiffImage.
// When the container is disposed all frames will be disposed automatically.
Aspose.Imaging.FileFormats.Tiff.TiffFrame firstFrame = new Aspose.Imaging.FileFormats.Tiff.TiffFrame(createOptions, 100, 100);
    
// Fill the entire frame with the blue-yellow gradient.
Aspose.Imaging.Brushes.LinearGradientBrush gradientBrush = new Aspose.Imaging.Brushes.LinearGradientBrush(
        new Aspose.Imaging.Point(0, 0),
        new Aspose.Imaging.Point(firstFrame.Width, firstFrame.Height),
        Aspose.Imaging.Color.Blue,
        Aspose.Imaging.Color.Yellow);

Aspose.Imaging.Graphics graphics = new Aspose.Imaging.Graphics(firstFrame);
graphics.FillRectangle(gradientBrush, firstFrame.Bounds);

// Create a TIFF image.
using (Aspose.Imaging.FileFormats.Tiff.TiffImage tiffImage = new Aspose.Imaging.FileFormats.Tiff.TiffImage(firstFrame))
{
    tiffImage.Save(dir + "output.tif");
}

The following example shows how to compose a mutlipage TIFF from individual raster images.

[C#]

Aspose.Imaging.ImageOptions.TiffOptions createTiffOptions = new Aspose.Imaging.ImageOptions.TiffOptions(Aspose.Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.Default);
createTiffOptions.Source = new Aspose.Imaging.Sources.FileCreateSource("c:\\temp\\multipage.tif", false);
createTiffOptions.Photometric = Aspose.Imaging.FileFormats.Tiff.Enums.TiffPhotometrics.Rgb;
createTiffOptions.BitsPerSample = new ushort[] { 8, 8, 8 };

using (Aspose.Imaging.FileFormats.Tiff.TiffImage tiffImage = (Aspose.Imaging.FileFormats.Tiff.TiffImage)Image.Create(createTiffOptions, 100, 100))
{
    // This is Font and Brush for drawing text on individual frames.
    Aspose.Imaging.Font font = new Aspose.Imaging.Font("Arial", 64);
    Aspose.Imaging.Brushes.SolidBrush brush = new Aspose.Imaging.Brushes.SolidBrush(Aspose.Imaging.Color.White);

    // Create 5 frames
    for (int i = 1; i <= 5; i++)
    {
        Aspose.Imaging.ImageOptions.PngOptions createPngOptions = new Aspose.Imaging.ImageOptions.PngOptions();
        createPngOptions.Source = new Aspose.Imaging.Sources.StreamSource(new System.IO.MemoryStream());

        // Create a PNG image and draw the number of page on it.
        Aspose.Imaging.FileFormats.Png.PngImage pngImage = (Aspose.Imaging.FileFormats.Png.PngImage)Image.Create(createPngOptions, 100, 100);
        Aspose.Imaging.Graphics gr = new Aspose.Imaging.Graphics(pngImage);
        gr.DrawString(i.ToString(), font, brush, 10, 10);

        // Create a frame based on the PNG image.
        Aspose.Imaging.FileFormats.Tiff.TiffFrame frame = new Aspose.Imaging.FileFormats.Tiff.TiffFrame(pngImage);

        // Add the frame to the TIFF image.
        tiffImage.AddFrame(frame);
    }

    // The image was created with a single default frame. Let's remove it.
    Aspose.Imaging.FileFormats.Tiff.TiffFrame activeFrame = tiffImage.ActiveFrame;
    tiffImage.ActiveFrame = tiffImage.Frames[1];
    tiffImage.RemoveFrame(0);

    // Don't forget to dispose the frame if you won't add it to some other TiffImage
    activeFrame.Dispose();

    tiffImage.Save();
}

The following example shows how to create a grayscale copy of an existing frame and add it to a TIFF image.

[C#]

string dir = "c:\\temp\\";

Aspose.Imaging.ImageOptions.TiffOptions createTiffOptions = new Aspose.Imaging.ImageOptions.TiffOptions(Aspose.Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.Default);

// Create a permanent, not temporary file source.
createTiffOptions.Source = new Aspose.Imaging.Sources.FileCreateSource(dir + "multipage.tif", false);
createTiffOptions.Photometric = Aspose.Imaging.FileFormats.Tiff.Enums.TiffPhotometrics.Rgb;
createTiffOptions.BitsPerSample = new ushort[] { 8, 8, 8 };

using (Aspose.Imaging.FileFormats.Tiff.TiffImage tiffImage = (Aspose.Imaging.FileFormats.Tiff.TiffImage)Image.Create(createTiffOptions, 100, 100))
{
    // The linear gradient from the left-top to the right-bottom corner of the image.
    Aspose.Imaging.Brushes.LinearGradientBrush brush =
        new Aspose.Imaging.Brushes.LinearGradientBrush(
            new Aspose.Imaging.Point(0, 0),
            new Aspose.Imaging.Point(tiffImage.Width, tiffImage.Height),
            Aspose.Imaging.Color.Red,
            Aspose.Imaging.Color.Green);

    // Fill the active frame with a linear gradient brush.
    Aspose.Imaging.Graphics gr = new Aspose.Imaging.Graphics(tiffImage.ActiveFrame);
    gr.FillRectangle(brush, tiffImage.Bounds);

    // Grayscale options
    Aspose.Imaging.ImageOptions.TiffOptions createTiffFrameOptions = new Aspose.Imaging.ImageOptions.TiffOptions(Aspose.Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.Default);
    createTiffFrameOptions.Source = new Aspose.Imaging.Sources.StreamSource(new System.IO.MemoryStream());
    createTiffFrameOptions.Photometric = Imaging.FileFormats.Tiff.Enums.TiffPhotometrics.MinIsBlack;
    createTiffFrameOptions.BitsPerSample = new ushort[] { 8 };

    // Create a grayscale copy of the active frame.
    // The pixel data is preserved but converted to the desired format.
    Aspose.Imaging.FileFormats.Tiff.TiffFrame grayscaleFrame = Aspose.Imaging.FileFormats.Tiff.TiffFrame.CreateFrameFrom(tiffImage.ActiveFrame, createTiffFrameOptions);

    // Add the newly created frame to the TIFF image.
    tiffImage.AddFrame(grayscaleFrame);

    tiffImage.Save();
}

This example shows how to save a raster image to the TIFF format using various options.

[C#]

saveOptions.BitsPerSample = new ushort[] { 8, 8, 8 };

saveOptions.ByteOrder = Aspose.Imaging.FileFormats.Tiff.Enums.TiffByteOrder.BigEndian;

// Set the LZW compression.
saveOptions.Compression = Aspose.Imaging.FileFormats.Tiff.Enums.TiffCompressions.Lzw;

// Allow to reduce the size of continuous-tone images.
// Currently this field is used only with LZW encoding because LZW is probably the only TIFF encoding scheme
// that benefits significantly from a predictor step.
saveOptions.Predictor = Imaging.FileFormats.Tiff.Enums.TiffPredictor.Horizontal;

// Set the RGB color model.
saveOptions.Photometric = Aspose.Imaging.FileFormats.Tiff.Enums.TiffPhotometrics.Rgb;

// For YCbCr, you can use one of the following choices:
// YCbCrSubSampling field   JPEG sampling factors
// ----------------------------------------------
// 1,1                      1x1, 1x1, 1x1
// 2,1                      2x1, 1x1, 1x1
// 2,2(default value)       2x2, 1x1, 1x1
// saveOptions.YCbCrSubsampling = new ushort[] { 2, 2 };

// All color components will be stored within a singel plane.
saveOptions.PlanarConfiguration = Aspose.Imaging.FileFormats.Tiff.Enums.TiffPlanarConfigs.Contiguous;

// Create a TIFF Frame of 100x100 px.
using (Aspose.Imaging.Image image = new Aspose.Imaging.FileFormats.Bmp.BmpImage(100, 100))
{
    // Fill the entire image with the blue-yellow gradient.
    Aspose.Imaging.Brushes.LinearGradientBrush gradientBrush = new Aspose.Imaging.Brushes.LinearGradientBrush(
            new Aspose.Imaging.Point(0, 0),
            new Aspose.Imaging.Point(image.Width, image.Height),
            Aspose.Imaging.Color.Blue,
            Aspose.Imaging.Color.Yellow);

    Aspose.Imaging.Graphics graphics = new Aspose.Imaging.Graphics(image);
    graphics.FillRectangle(gradientBrush, image.Bounds);

    image.Save(dir + "output.tif", saveOptions);
}
